If you see this I hope you are doing great!! If you by any chance know this may you please help me?​

x = 8

y = 79

Step-by-step explanation:

Remark

The ys are the same value for each equation. Therefore you can equate the right hand side of both to each other.

Solution

8x + 15 = 3x + 55                Subtract 15 from each side.

    - 15 =      -   15

8x = 3x + 40                        Subtract 3x from both sides.

3x = 3x

5x = 40                               Divide both sides by 5

5x/5 = 40/5

x = 8

Now use one of the original equations to find y

y = 8x + 15

y = 8*8 + 15

y = 64 + 15

y = 79

y=8x+15

y=3x+55

y=8x+15

8x+15=3x+55

y=8x+15

x=8

y=8×8+15

x=8

y=79

x=8

(x,y)=(8,79)

I really hope it helped! :)

answer: the common difference is -0.10
